Oill filled pressure gauge is filled with damping liquid good  performance of 

shock proof.This sort of maters  is suitable for locations  where the  pressure

  of  medium  changes   intensely  and pressure shock proof exists, or pressure

 is released suddenly in the course of manufacturing, or working environment 

shock largely. The meter can measure average of gas and liqu id mediums.Thus 

damage to  meter induced byintensive fluctuation and environmental shock can 

be over come smoothly and accuracy  of freading is ensured.
